View Full Version : Stereo DVD AC3 to stereo AAC is undersized

I'm trying to encode stereo AC3 that was ripped off of a DVD (2h58min long) to 128kb/s ABR AAC-LC. I converted the AC3 to WAV using NicAC3Source(), AmplifydB() and SoundOut() in AviSynth (to 16bit Microsoft WAV), listening to the WAV, it sounds perfect and is of correct length/size.

I then use Nero Digital Audio v1.1.34.2 to convert the audio:

neroAacEnc_SSE.exe -br 128000 -2pass -lc -if Stereo.wav -of Stereo.mp4

The resulting audio is very undersized (around 28kb/s according to MediaInfo), is of correct length, and sounds like utter crap. Adding the -ignorelength switch does not help.

I'm kind of puzzled as to what's going on. Thanks for any help.

Hi!

Why don't you simply use the BeLight GUI/BeSweet (0.22Beta9) to DIRECTLY convert the .AC3 to AAC? (No need for intermediate .WAV)
